Method for obtaining a growth medium for growing plants comprising taking organic waste suitable to the plants to be grown, mixing it to obtain a homogeneous material and reducing its microbial activity, incinerating organic waste suitable to the plants to be grown to obtain ash, a source of minerals suitable for the cultivation of said plants, and incubating the homogeneous material with the ash to restart the microbial activity, initiating the mineralization of the material, and obtaining a ready-to-use growth medium.

A method for forming soil enhancement includes forming microbes in a concentrated form of at least 110.sup.7 cfu/ml (colony-forming units per milliliter); and dry forming the microbes onto humic acid.

A biogas collection and purification system that includes a plurality of sources of biogas and a network of conduits configured to convey the biogas from the sources to a central processing facility for processing the biogas into methane. The central processing facility removes impurities to convert biogas to biomethane and may include an H.sub.2S removal stage; an activated carbon scrubber; a gas drier; and a carbon dioxide removal stage. The facility also has a biomethane gas compressor configured to deliver the biomethane for use in power plants, for CNG production. Ancillaries to the system include fuel cells for direct electricity generation from biogas/biomethane.

The invention provides an efficient system for treating livestock waste, particularly waste from cattle or pig farming. The new facility and method employ special transfers of slurry streams through ASBR, SBR, and a unique pretreatment reactor, resulting in treated water, quality compost, and biogas.
